Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT TORQUE SENSOR CONNECTOR AND WIRING HARNESS

•  Switch the ignition off.

•  Disconnect the torque sensor connector.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [(E)].)

•  Are the connector connection, connector pins, and wiring harness normal?

Yes

Go to the next step.

No

Replace the steering column and perform the repair completion verification.

(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [(E)].)

2

INSPECT TORQUE SENSOR

•  Using the M-MDS, perform the PID inspection for the EPS control module.
(See PID/DATA MONITOR INSPECTION.)

(See PID/DATA MONITOR TABLE [ELECTRIC POWER STEERING (EPS) (E)].)

―  STR_TRQ_MAIN_1

―  STR_TRQ_MAIN_2

―  STR_TRQ_SUB_1

―  STR_TRQ_SUB_2

•  Do the PIDs indicate as followings?

―  STR_TRQ_MAIN_1 and STR_TRQ_MAIN_2

•  Steered left: Changes to 0—positive

•  Steered right: Changes to 0—negative

―  STR_TRQ_SUB_1 and STR_TRQ_SUB_2

•  Steered left: Changes to 0—negative

•  Steered right: Changes to 0—positive

Yes

Go to the next step.

No

Replace the steering column and perform the repair completion verification.

(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [(E)].)

Repair completion verification 1

VERIFY DTC TROUBLESHOOTING COMPLETED

•  Using the M-MDS, clear the DTC from the EPS control module.
(See CLEARING DTC.)

•  Using the M-MDS, perform the EPS control module DTC inspection.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the EPS control module.
(See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [(E)].)

Go to the next step.

No

Go to the next step.

Repair completion verification 2

VERIFY NO DTC IS PRESENT

•  Are any DTCs present?

Yes

Go to applicable DTC inspection.

(See DTC TABLE [ELECTRIC POWER STEERING (EPS) (E)].)

No

DTC troubleshooting completed.
